In iOS 5 there are three ways to be notified of an alert. You can have an audio alert or a vibrating alert and there is also now visual alerts via flashing of the LED.
This third option is new in iOS 5 and it is turned off by default. To turn it on go to
Settings --> General --> Accessibility --> LED Flash for Alerts . And then turn "ON"
Sadly at this time it is not customizeable, where you could have different flash patters - like you can for vibrations. Nor can you pick and choose which contacts get the flash alerts. Hopefully those options will be added in the future.
